To accomplish this, create a function called runMenu$()$ and call it from the main$()$

function. Inside the runMenu$()$ function, ensure that the user can select any of the

displayed options as often as they desire before ultimately ending the program. It is

important to validate the user's input so that only the displayed options can be chosen.

Each option should be processed numerically for easier selection. For instance, option $[1]$ can be associated with "Ending the Program," option $[2]$ with "Displaying 'Game Rules' Information," and so on
